Biofunctional Properties of Guava Leaves Herbal Tea Powder: A Cholesterol Modulating Potential

Ayurveda emphasizes maintaining balance among doshas (Vata, Pitta, Kapha), dhatus, and malas to support overall health, with cardiovascular disorders (CVDs) often resulting from systemic or organ dysfunctions. Psidium guajava (guava) leaves, recognized in traditional medicine for their Hridya (cardiotonic) properties, exhibit antioxidant, anti-inflammatory, hypotensive, and cardioprotective activities. Experimental studies demonstrate that guava leaf extracts mitigate oxidative stress, modulate intracellular calcium, and restore cardiac function during ischemia-reperfusion injury, highlighting their potential in preventing hypertension and other CVDs. This study aimed to develop and standardize a guava leaf-based herbal tea with cardioprotective potential.
